i This invention relatesto a'stove, which means are provided for? conveying thedisintegrated lign-ite cokeradiallyoutwards from: the; delivery aperture of the fuelreceptacle to a; plate supporting the-burning coke. The bottom-.ofzthe fuel receptacle is formed asa hopper, and a, cdnveying member, formed preferably byis arranged below the deliV- ery opening of said; hopper-shaped bottom. Also the fuel plateis,. 'as a *rule, hopper-V shaped, and the I disk with its blades; is: located between said two hoppers. The fuel by the intermediary ofthe said conveying member, and the means member extends through the fuel-receptacle .to the space above the stove, all: asinore fully described hereinafter. f The invention is illustrated diagrammati cally and by way of example-in the ac'com panyingdrawing i n'whi'ch,
